Retry giving up too fast

I am making some initial backups using Vertical backup 1.1.1 to B2. The backup is failing a little too often for my taste. Perhaps introduce options to allow more retries (and perhaps an exponential backoff mechanism to not hammer the cloud server)?

Since Vertical is intended for large backups, I would expect it to not give up even if some storage gives problems for hours (especially with B2 having an entire hour/week standard maintenance window) - I am not planning on backing up more than once/week or /month (using Duplicacy for individual file backup on a shorter cycle), so I would prefer that the backup almost always succeeds; now it almost always fails.

It is already doing exponential backoff but the maximum number of retries is fixed at 8. I'll add an environment variable to set the number of retries.

Thanks, looking forward to it.

Version 1.1.2 allows the number of retries to be set by the environment variable VB_MAX_RETRIES. The default is 8.
